Abstract

The invention relates to a sterilization composition containing pyrimethanil and methoxy acrylate compounds. The composition includes an active component A and an active component B, wherein the active component A is selected from pyrimethanil, the active component B is one selected from kresoxim-methyl, pyraclostrobin, trifloxystrobin and fluoxastrobin, and the weight ratio of the active component A to the active component B is 1:80-80:1. The above effective active components are added to corresponding assistants to prepare a wettable pulvis, a water dispersible granule, a suspension agent, a suspension emulsion, an emulsion in water and a microemulsion which are used for controlling gray mold, powdery mildew, Cladosporium cucumerinum, downy mildew, rice blast, the rust disease, anthracnose, bacterial wilt, Rhizoctonia solani, leaf spot, the eqpidemic disease and brown patch, can tolerate rain wash and have an obvious synergistic effect.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a fungicidal composition containing pyrimethanil and methoxyacrylate compounds on crop diseases. technical background [0002] Pyrimethanil, English name: Pyrimethanil, molecular formula: C 12 h 13 N 3 , Chemical name: N-(4,6-dimethylpyrimidin-2-yl)aniline. [0003] Pyrimethanil is an anilinopyrimidine fungicide, which prevents the infection of germs and kills germs by inhibiting the production of germ-infecting enzymes. At the same time, it has the function of systemic conduction and fumigation. After spraying, it can quickly reach the parts of the plant such as flowers and young fruits that cannot be reached by spraying to kill germs. It mainly inhibits the elongation of germ tubes and mycelial growth of Botrytis cinerea. It also has a certain inhibitory effect on the spore germination of Botrytis cinerea within a certain period of time. [0004] Kresox...
